A highly porous material, this material can have a surface area significantly over 200 square metres/g. Very suitable for use as a filter of fluoride, arsenic and selenium in drinking water
It has a high surface area which adsorbs vapors without any change in form. Will not soften or disintegrate easily when immersed in water.
Dew points to -40°F and lower may be achieved depending on dryer design and operating conditions.
The 1/8” (2-5mm) bead is the size most frequently used in regenerative dryers.
The 3/16” (4-8mm) bead is used when pressure drop and surface area requirements fall between 1/8” and 1/4” material. It is suitable for most systems.
The 1/4” (5-10mm) is used both as a pre-bed material to support large desiccant beds or as a buffer for silica gel beads. Pressure drop is slightly lower than 1/8” (25mm) material.
If size is not known or specified, the 1/8” (2-5mm) size is usually satisfactory.
Product Benefits:
- High adsorption capacity. With high surface area and excellent pore distribution, has a high water adsorption capacity. This reduces initial cost, energy consumption and operating costs through smaller bed sizes and/or longer operating cycles.
- Low abrasion. Insures less dusting during tower depressurization or loading. Low abrasion means low pressure drop and a reduced chance of plugging the afterfilter.
- Resists liquid water. Water slugging due to upstream failure of aftercooler, separators or drain traps will not fracture. The adsorption capacity of the desiccant can be restored after complete regeneration.
- High crush strength. High crush strength, which limits dusting, is important during loading of desiccant towers. High crush strength makes effective as a prebed material when used with other types of desiccants.
- Uniform bead sizes. Is a uniformly sized bead. It provides low pressure drop to minimize channeling and ensures utilization of the full bed column section.
